What it looks like

A Stocks or Geography cell shows #BUSY!
The error clears after a refresh
Several linked cells fail at the same time

Why #BUSY! happens

Temporary high demand on the data provider.
Too many linked data requests at once.
A slow network or proxy.
The workbook is recalculating while a refresh is still running.

How to fix #BUSY!

1
Wait and refresh once
Pause for a minute, then refresh the data type. Repeated refresh requests can make the problem worse.
2
Reduce the number of linked cells
Convert values you no longer need to static values, or move the data type lookups to a smaller helper sheet.
3
Check service status
If every linked cell is failing, check Microsoft 365 service health or try another network.

#VALUE!Wrong value type#VALUE! means Excel expected a number, date or logical value but found text, an empty cell or a value from another data type. The fix is to convert the input, remove hidden characters, or guard the calculation with IFERROR.#REF!Broken cell reference#REF! means a formula points to a cell, row, column or sheet that no longer exists. It usually appears after deleting rows or columns, moving a sheet, or pasting a formula into a workbook that does not contain the referenced sheet.#N/ALookup value not found#N/A means a lookup or match function could not find the value. The value may be missing, spelled differently, stored as text instead of a number, or surrounded by spaces. Use exact-match mode and return a clear fallback.#DIV/0!Division by zero#DIV/0! appears when a formula divides by zero or by an empty cell. Excel treats a blank denominator as zero. Check the denominator, exclude blank rows, or return a controlled blank with IFERROR.
